Correct Answer: Option B
Explanation

Cross-pollination is a type of pollination that produces healthier offspring, viable seeds, and new varieties.

Cross-pollination involves the transfer of pollen from the anther of one flower to the stigma of a different flower. In contrast, self-pollination is when pollen is transferred within a flower or between flowers on the same plant. Self-pollination is effective in a stable environment, but it can lead to weak offspring that are less adapted to the environment. 

There is an explanation video available below.
